Member Function Documentation

get()

virtual double geos::algorithm::distance::DiscreteFrechetDistance::MatrixStorage::get ( std::size_t i, std::size_t j ) const

pure virtual

Gets the matrix value at i, j

Parameters

i	the row index
j	the column index

Returns

The matrix value at i, j

Implemented in geos::algorithm::distance::DiscreteFrechetDistance::CsrMatrix, geos::algorithm::distance::DiscreteFrechetDistance::HashMapMatrix, and geos::algorithm::distance::DiscreteFrechetDistance::RectMatrix.

isValueSet()

virtual bool geos::algorithm::distance::DiscreteFrechetDistance::MatrixStorage::isValueSet ( std::size_t i, std::size_t j ) const

pure virtual

Gets a flag indicating if the matrix has a set value, e.g. one that is different than MatrixStorage defaultValue.

Parameters

i	the row index
j	the column index

Returns

a flag indicating if the matrix has a set value

Implemented in geos::algorithm::distance::DiscreteFrechetDistance::CsrMatrix, geos::algorithm::distance::DiscreteFrechetDistance::HashMapMatrix, and geos::algorithm::distance::DiscreteFrechetDistance::RectMatrix.

set()

virtual void geos::algorithm::distance::DiscreteFrechetDistance::MatrixStorage::set ( std::size_t i, std::size_t j, double value )

pure virtual

Sets the matrix value at i, j

Parameters

i	the row index
j	the column index
value	The matrix value to set at i, j

Implemented in geos::algorithm::distance::DiscreteFrechetDistance::CsrMatrix, geos::algorithm::distance::DiscreteFrechetDistance::HashMapMatrix, and geos::algorithm::distance::DiscreteFrechetDistance::RectMatrix.
